In any other fiction, the lake can be said to be haunted by a hag.
In SM Stirling's A Meeting At Corvallis, it is named after a politician whose surname was Hagg but later is said to be haunted by a hag.
In ambiguous fiction, there can be unconfirmed hints of a haunting.
In psychological fiction, a character can see or sense a hag without implying the literal existence of such an entity.
In science fiction, there can be a scientific rationale of a being resembling a hag.
I think that that exhausts the possibilities. As usual, there were more of them than expected.
